IMPROVEMENT IN REVERSING-LINK-MTION ENGINES.

Specification forming part of Letters Patent N0. 135.410, dated February 4, 1873.

To all whom it may concern:

Be it known that I, THOMAS L. CROWLEY, of Parker township, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Reversin g-Link-Motion Engines at a distance; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, which form a part of this specilication.

My invention relates to the regulation and control of the motion of steam-engines at a distance therefrom.

In the accompanying drawing, Figure lis a side elevation, showin g all the devices used in my improvement. Fig. 2 is a detail, showing` the construction of device for holding the. lever in position.

Located in the derriclr, in any suitable position, are two pairs ot' cross-legs, A A, with a shaft, e', connecting them, and supported with stays a or other means. The lever B is borne by the said sha-ft. To the extremity, or thereabout, of saidY lever B is attached a crosspiece, b, of about the same length, and which is held in position by stays 02.113. The said lever B and the cross-piece b are perforated at the point of their connection, through which perforation the shaft a passes, thus supporting the said lever and cross-piece, and forming a bearin g for them. The said lever B is held in any desired position by means of an upright leg, d, together with a movable leg, d1, attached to it at the lower extremity by means of a bolt and at the top by a threaded spindie, d?, with a handle attached. Running from each extremity of cross-piece b is a stitt rope, wire, or chain, C1, or other suitable means of connection, to the link G of the steam-engine. This rope, wire, or chain O1 runs over pulleys or other device situated above and below said link. The mode of attaching the rope, wire, or chain O1, or their equivalent, to the upper and lower ends ofsaid link is accomplished by means of clamps bolted thereon, with a pin or other suitable projection on each side, to which a doubled strip of iron or other nieta-l, C?, is loosely attached.

It will be clearly seen that by raising or lowering the lever B the link of the engine, to which the connecting-ropes O1 are attached, is also raised and lowered at will, thus securing complete control over the motions of the engine, holding it stationary, if necessary, by placing the lever B in a horizontal position.

I do not confine myself to the particular form of lever, or to the means of connecting the same to the link of the engine.

By the use of my invention a great saving in labor is effected, as the engineer can assist in the operations in the (lerrick and still have control over his engine.

Hy improvement renders unnecessary the set-screw upon the link now in general use upon oil-well engines.

My improvement gives instantaneous reversal or stoppage ot the engine. It is easy of construction, of small cost, and ot' great service at an oil-well.

The said leverB, cross-piece b, support A, and legs d and d1, with their attachments, may be constructed of iron, wood, or any suitable material.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l.' The link O ot' a steam-engine, in combination with the ropes or chains O1 C1 and lever B b, arranged to operate substantially as specilied.

2. The elements enumerated in the first claim, in combination with the clamping devices composed of the bars d d1 and screw d2, substantially as and for the purpose specied.

In testimony that I claim the foregoing as .my own I affix my signature in presence of two witnesses. v
